21.2.3.2: TASK_START Extension

The TASK_START extension directly corresponds to the task_start directive. If this extension is defined in any static or dynamic extension set and a task is being started, then the extension routine will automatically be invoked by RTEMS. The extension should have a prototype similar to the following:

procedure User_Task_Start (
   Current_Task : in     RTEMS.TCB_Pointer;
   Started_Task : in     RTEMS.TCB_Pointer
);

where current_task can be used to access the TCB for the currently executing task, and started_task can be used to access the TCB for the dormant task being started. This extension is invoked from the task_start directive after started_task has been made ready to start execution, but before it is placed on a ready TCB chain.
